The paper presents the results of a study of metasedimentary rocks in the Bamble Terrane, S. Norway. These are of Mesoproterozoic age and were deposited in an early phase in the evolution of the Terrane judging from deformational features, cross-cutting intrusive rocks and widespread metamorphism. Lithologically speaking, the main sedimentary units consist of quartzites (former sandstones), meta-pelites (former slamstones, argillaceous sediments, some partially quartz-bearing) and occasionally, calcsilicate beds. Small amounts of marble (former carbonate-rich sedimentary rocks) occur often in association with the meta-pelitic beds. Some meta-greywacke beds (possibly pyroclasts of volcanic origin) are also reported (Morton 1971).
